Answer:
12.0 cm
Step-by-step explanation:
The Pythagorean theorem applies:
(12 cm)² +b² = (17 cm)²
b² = (289 -144) cm² = 145 cm²
b = √145 cm ≈ 12.04 cm
b ≈ 12.0 cm . . . . rounded to 1 decimal place
If the amount of members are y, then the total number of people who attend is x+y=19. In addition 11*y (since it costs 11 dollars per member)+13*x=209. Subtracting x from both sides in the first equation, we get y=19-x. Plugging that into the second equation, we get (19-x)*11+13*x=209. Multiplying it out, we get 201-11x+13x=209. Subtracting 201 from both sides, we get 2x=8 and by dividing both sides by 2 we get x=4
